No Start SC300
Just sharing my adventure today.
The car ran fine. I was attempting to adjust the TPS to see if that was the random stall problem I had. After adjusting the TPS voltage signal the car started then stalled. So the car would crank, then catch for a second or a few and shut off. Then cranking more times, it would not catch at all. At first it would catch for a few seconds each time I adjusted the TPS in a certain voltage range so I thought it was due to the TPS. An hour later I decided to give up on the TPS and move to engine light, spark, fuel and timing. Engine light was a continuous blinking so no luck there. I had spark and timing belt was still timed correcting. At the fuel pump I didnt have 12v. Switched the relay with the defroster. No luck. I was loosing power at the fuel ecu. So did the 12v bypass and shes all good now. Starts up. Tomorrow I will finish adjusting the tps, idle and the small things.

Once I got the car running, I used the idle screw to drop my rpm's down to around 600 then rechecked to make sure my tps was still in spec. Running so much better now, I think my fuel ecu was cutting in and out while I was driving before or keeping it at low voltage. I use to have random bogs while driving.
